Is there any reason why you have a partition on the device at all? My
experience is that USB storage devices have their filesystem on the
device, i.e. there is only /dev/sda no /dev/sda1.

If you add entries to /etc/fstab and want users to be able to mount the
device you need to add 'user' to the options. I like using 'pmount'
instead of editing /etc/fstab.

Are both devices created (/dev/sda and /dev/sda1) when you plug in your
player?
Do you have any udev rules in place relating to the player (or /dev/sda1
in general)? It seems Gnome's automatic mounting of devices leaves
devices alone if you muck around with the udev rules a bit (I think of
this as a feature, not a bug :-).

I've spent a bit of time configuring my USB stick to appear exactly the
way I want it when plugging it in:

At first I didn't use Gnome's volume manager, but later I learned to
love the beast ;-).

Hope it helps...
